Product Lineup

Open Loop





How it Works

In an open loop current sensor, the magnetic flux created by the primary current (If) is concentrated in a magnetic circuit and measured using a hall device. The output from the hall device is then signal conditioned to provide an exact (instantaneous) representation of the primary current.

Closed Loop




How it Works

The magnetic flux generated by the primary current (If) is balanced or compensated by a current generated in the secondary winding. This compensation current is generated by signal conditioning electronic circuity using the output of the Hall Element. The compensation current is then an exact, or instantaneous, representation of the primary current divided by the number of turns in the secondary winding.

Flux Gate (FG)


How it Works

The magnetic flux created by the primary current (If) is balanced through a secondary coil using the magnetic probe device to provide a feedback and associated electronic circuitry to drive a compensating current in the secondary coil. The secondary (compensating) current is an exact (instantaneous) representation of the primary current and is converted to a voltage through an internal high precision resistor.
